Hi thanx for giving us that VST for free! (tested the VST2 version).
I tried it a bit and what I noticed first is the clear GUI/concept with nice presets. Compared to other "Rigs" its very simple to use and flexible. Effects seem to be limited to dynamics. There is also a possibility to choose impulse response which I didn't try, maybe not implemented in the free version? But in combination with other (free) plug-ins its really great.
